I made an installment purchase and my card's available balance got zeroed out, how long does this take to clear?

I made a computer purchase on my Apple Card a week ago. After the order was placed I noticed my available balance on my card read $0 when it had been $4k+ beforehand. I contacted Apple Card support twice on it, first time they assured me it would reset by Monday (I made the purchase on a Saturday.) Second time I contacted support the representative told me the card should reset by the end of the week. It's now Friday and still my order is in processing and my card is still reflecting $0 balance.

Has anyone else had this happen to them and if so, how long did this end up taking to resolve for you?

Thanks in advance!
